Republican Delegate Neil Parrott, R-Washington County, who is the chairman and founder of Marylandpetitions.org, announced Wednesday that a coalition of Maryland gun groups, with the blessing of the National Rifle Association, has decided to let the courts decide if Maryland's sweeping gun control bill that passed this session should stay on the books.

"This is a constitutional right that shouldn't just go to the people to vote. We have to stand up for every one of our constitutional rights," Parrott said.

The forthcoming lawsuit, which 11 News learned the NRA's lawyers are working on, will focus on the new gun licensing and firearms training course fees included in Maryland's gun control bill.

"With the Second Amendment, everybody seems to think it's OK to go ahead and put infringements upon it, but clearly the Constitution says you can't infringe upon it, and placing a fee on the ability to exercise that right is unconstitutional," said Delegate Mike Smeigel, R-Cecil County.

In the wake of the Newtown, Conn., elementary school massacre, the Democratic-controlled State House and Senate passed a set of measures that would give Maryland some of the toughest gun laws in the nation. The bill bans the sale of assault rifles, limits magazine sales to 10 bullets and requires potential gun buyers to submit fingerprints to Maryland State Police and get a license to buy a handgun.

Supporters of the bill, which officially becomes law when O'Malley signs it and will become effective in October, are ready for another round of debate over the issue.

"Marylanders overwhelmingly support this. According to some polls, over 80 percent of Marylanders support fingerprinting licensing of handgun purchasers. Why? Because it saves lives," said Vinny DeMarco of the group Marylanders to Prevent Gun Violence.

Officials from the Maryland Attorney General's Office told 11 News they believe what they called administrative fees are constitutional. They recalled a 1941 U.S. Supreme Court case in which justices upheld a case where the government charged parade fees, essentially making people pay to exercise their First Amendment rights.
